During data collecting process three standard scales such as The ADHD self-report scale, the Revised Conflict Tactics Scale and the Dyadic Adjustment Scale were employed and significant relationships among all three variables were found and the level of the ADHD symptoms was clearly related to dyadic satisfaction.
